Resin identification code
The code below is called the SPI resin identification coding system, developed by the American Society of the Plastics Industry[?] in 1988.
Most plastics can be recycled, but because of the difficulty and expense of sorting, collecting, cleaning and reprocessing it is only at the moment economically viable to recycle PETE, PVC and HDPE.
Thermoplastics[?] can be remelted, but thermosetting plastics[?] can only be crushed and used as insulation.
As you can not mix plastics together they have to be separated into their different polymer types.
